apache-13 error appears at package lifecycle with maven - java

I created a simple Maven project on a rasberry pi and my project connects to a mysql database to be able to insert in, so to handle the dependencies and the plugins I have this pom.xml but when I try to make mvn package I have the following error knowing that it worked a first time and that it did well insert in my database I tried to look at several examples on the internet without result. thank you in advance
The error:
[ERROR] Plugin org.apache.maven.plugins:maven-surefire-plugin:2.17 or

If you are calling the variable jdk.version with ${jdk.version} you should define it in your pom.xml. You can simply add the new variable between your <properties>...</properties> tag like it:
<properties>
<jodatime.version>2.5</jodatime.version>
<log4j.version>1.2.17</log4j.version>
<jdk.version>1.8</jdk.version>
</properties>
You can read more about the pom properties: pom properties documentation

suggestions to solve the problem ??

I had the same problem. I am using Eclipse Jun 2021 release. The problem got resolved after manually configuring one of the recent war plug-ins in POM.xml.
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.3.1</version>
</plugin>

I experienced the same issue after upgrading from JDK 1.8 to JDK 17 and I solved it by upgrading the plugin version.
Before:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>2.3</version>
</plugin>
After:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.3.1</version>
</plugin>

if you want to deploy the war. what worked for me is both
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.3.1</version>
<configuration>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
and
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<inherited>true</inherited>
<version>3.8.1</version>
<configuration>
<source>16</source>
<target>16</target>
<compilerArguments>
<endorseddirs>${endorsed.dir}</endorseddirs>
</compilerArguments>
</configuration>
</plugin>
Please note the versions.

You can fix it by changing the JDK in your projects to JDK 14. Left-click on your project and go to properties -> build -> compile . Change the JDK to version 14. If you don't have JDK 14, you can manage it there by clicking Manage Java Platforms. The download of the JDK is here.

Your pom.xml like this will work.

I have solved this by simply going in the Jenkins global tool configuration and changing the path of JDK to /usr/local/Cellar/openjdk#11/11.0.10.
Previously it was /usr/local/Cellar/openjdk/16.0.1 in my local machine MAC.

I had this exact same issue. After updating the POM file, I needed to delete my .m2/repository folder before running mvn install for the project.

I had the same problems and I resolved changed the version 2.3 to 3.3.1
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.3.1</version>
<configuration>

Problem has been resolved by stopping the Tomcat server
sudo systemctl stop tomcat
so as to allow Netbeans to run it. If the server is already running when Netbeans tries to deploy an app Netbeans will display the delopy failed message.

I resolved this error by adding following part in pom.xml
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-war-plugin</artifactId>
<version>3.3.1</version>
<configuration>
<source>1.8</source>
<target>1.8</target>
<failOnMissingWebXml>false</failOnMissingWebXml>
</configuration>
</plugin>
</plugins>
</build>
apart from that i added maven configuration properties
<properties>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
and here is my entire file as following

Maven - Invalid signature file digest for Manifest main attributes

New to java and Maven.
When trying to add dependancy to the package pulsar-functions-local-runner I am getting an error:
Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.2-beta-5:assembly (make-assembly) on project java-function: Execution make-assembly of goal org.apache.maven.plugins:maven-assembly-plugin:2.2-beta-5:assembly failed: Invalid signature file digest for Manifest main attributes

Well i guess they made some change in the jar of 2.7.0 because changing to pulsar-functions-local-runner 2.6.0 solve the issue

Remove pulsar-client from maven, and add pulsar-common. pulsar-common has the pulsar-client-api. There is a serious conflict between pulsar-client and pulsar-common.

Include dependency in jar on maven package

I'm developing an application with maven.
I need to package it using mvn clean package to generate a jar.
But when I run my application I've got this Exception :

As you can see I already tried to add the main class. I also added the dependency maven-jar-plugins, but I still get an error messagen when I try to compile the project:
Plugin org.apache.maven.plugins:maven-jar-plugin:1.8.1 or one of its dependencies could not be resolved: Failed to read artifact descriptor for org.apache.maven.plugins:maven-jar-plugin:jar:1.8.1: Failure to find org.apache.maven.plugins:maven-jar-plugin:pom:1.8.1 in http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the update interval of central has elapsed or updates are forced -> [Help 1]
To see the full stack trace of the errors, re-run Maven with the -e switch.
Re-run Maven using the -X switch to enable full debug logging.

What am I doing wrong here? How to fix this?

What I do in one project of mine is to use the maven-jar-plugin and the maven-assembly-plugin
The result is an executable fat-jar.

After this just it the clean and build button in netbeans and search for something
with assembly file: PATH_TO_JAR/KBSE-CDI-Testprogram.jar

There is no version 1.8.1 of maven-jar-plugin.
Here the list of all available versions of maven-jar-plugin : https://mvnrepository.com/artifact/org.apache.maven.plugins/maven-jar-plugin
You have to update version into an earlier version.
Example with the latest version :

Unable to find a suitable main class, please add a 'mainClass' property, Spring boot

<version>0.0.1-SNAPSHOT</version>
</parent>
<artifactId>JhipsterSubmodule1</artifactId>
</project>
I have googled but not found any solution please help in this regard!

In my case I had in main pom:
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>2.0.3.RELEASE</version>
</parent>
which includes plugin spring-boot-maven-plugin.
I had to add to main pom to skip it:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<skip>true</skip>
</configuration>
</plugin>
and then in module with ma Application class:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<skip>false</skip>
</configuration>
</plugin>

I believe the issue I was having is similar to yours. I have a multi module app using Spring Boot and only one Application.java (with main method).
I was struggling with it trying to start it up using Maven and I got the same result as yours (unable to find a suitable main class).
I spent several hours trying and changing stuff and after adding the property mainClass to the pom, it couldn't find it.
Then I decided to run the project not from the root project but from the project where the Application class is.
By doing this I was able to start up Spring Boot and everything works like a charm.
Updated
If you want to package the whole thing to be executed with java -jar file you can run the command below from the root project:
mvn clean package spring-boot:repackage
Don't forget to add the spring-boot-maven-plugin to your pom.

Remove the maven build plugin code from the parent pom, which will be similar to the below, the below snippet should be only in the sub module pom where you have main class for spring boot application:
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</build>

I solved this by two steps:
In the parent module folder, run mvn install
Go to the sub module folder which contains the mainClass you need, run mvn clean spring-boot:start

Maybe you forgot to specify the main class to start.
In pom.xml:
<properties>
<start-class>com.ishanitech.controller.Application</start-class>
</properties>

If you are using IntellJ IDEA, maybe you can do it like this:
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<mainClass>add.your.main.class.application.reference.here</mainClass>
</configuration>
</plugin>
This solved my error.

Do you have a class in your app with a main method like:
public static void main(String[] args) {
SpringApplication.run(YourApplication.class, args);
}
Or do you even have multiple classes with main methods, in which case Spring can't figure out which one to use?

mvn clean spring-boot:start
…will give you the same error.
mvn clean package spring-boot:start
…is going to fix the issue by building the artifact before running sprint-boot:start.

If you don't want to create a fat jar, you can add follow lines in your pom.xml:
<properties>
<spring-boot.repackage.skip>true</spring-boot.repackage.skip>
</properties>

The issue is that spring looks for the main class in all modules of a multi module application.
If you have a multi-module application just add this to pom.xml of other modules which do not have the main class
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<skip>true</skip>
</configuration>
</plugin>
And main Class module pom.xml add
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<skip>false</skip>
</configuration>
</plugin>
Side note: Try to exclude didn't work for me

Use <pluginManagement> tag above the <plugins> tag
<pluginManagement>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
</plugin>
</plugins>
</pluginManagement>

If you are trying to run a mvn spring-boot:run or just a mvn (as you seem to use JHipster and this is the way they wire it as default goal) in the root of your project, it is normal that if fail according that I think it can only be used in a plain spring boot project.
As your parent project seems to have severals Spring-Boot webapps, I guess that each one have their own main() launch class, and that you are just using a parent pom to factorize your poms and be able to package all your applications individually via a single command.
So, in that case, just run a mvn package, and not a mvn nor a mvn spring-boot:run.

I have also faced the same problem, but by adding the below line in my pom.xml I resolved the issue for my project:
<properties>
<start-class>com.hls.om.wp.AgencySearch</start-class>
</properties>
where the AgencySearch class has the main method for running the spring boot application.

If you follow the official guides and clone repository to local, then you got to folders, the guides let you cd initial, don't do that, cd complete and there will be no problem.

I had the same issue. In my case it was because I had my main class in a package that was not "parent" to my other packages which contained Controllers, Entities, etc. Something like this:
+- com.domain.myapp.app
| \- Application.java
+- com.domain.myapp.controllers
| \- AppController.java
+- com.domain.myapp.entities
| \- AppEntity.java
+- com.domain.myapp.services
| \- AppService.java
+- com.domain.myapp.repository
| \- AppRepo.java
The solution was to move my main class to a package which is hierarchily on top of the other packages since Spring Boot automatically searches this package and all sub-packages for classes with #Entity, #Component, #Service, #Repository annotations. The result was something like this:
+- com.domain.myapp
| \- Application.java
| +- com.domain.myapp.controllers
| | \- AppController.java
| +- com.domain.myapp.entities
| | \- AppEntity.java
| +- com.domain.myapp.services
| | \- AppService.java
| +- com.domain.myapp.repository
| | \- AppRepo.java
Hope it helps!

The only way that worked is to exactly have these respectively in your parent and module pom.xml:

In my multi-module project, I did a cd into the sub-module and I used Maven's exec:java goal instead of spring-boot:run.
mvn clean package exec:java -Dexec.mainClass="a.b.c.Application"
For me, this was sufficient, but I'm not sure what spring-boot:run does differently.

You can fix the problem by specifying the location of main as follows:
mvn spring-boot {com.ishanitech.controller.Application}:run

I did as following and it resolved
<packaging>war</packaging>
<properties>
<java.version>1.8</java.version>
<maven.compiler.target>1.8</maven.compiler.target>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.test.skip>true</maven.test.skip>
</properties>
<build>
<plugins>
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<source>1.8</source>
<target>1.8</target>
<skip>true</skip>
</configuration>
</plugin>
</plugins>
</build>

The solution is change the pom.xml file
from this
<packaging>pom</packaging>
to this
<packaging>war</packaging>
or another value that you need depending of your deployment method.
